YHM’s line of sRx products were designed with ease-of-use and aesthetics as the top priorities and that is no different for the YHM sRx Q.D. Adapter (YHM-4400). This Low Profile Q.D. Adapter/Mounting Interface attaches to the industry standard (HUB) 1-3/8” x 24 threads. It features an internal taper seal in front of the threads-that locks your suppressor on and forms a tight seal to contain gasses while in-use. This means no gasses or debris can build up on the threads.

The sRx Q.D. Adapter must be paired with one of YHM’s sRx Muzzle Devices (4405's 4405-MB's 4401-MB's and 4445 muzzle devices).

The sRx Q.D. Adapter adds minimal length and weight to the suppressor set up while also allowing you to reap all the benefits of the new YHM sRx System-when used in conjunction with a YHM sRx Muzzle Device. The full YHM sRx (Suppressor Rx) System will be the obvious choice for someone looking for a sleek low-profile suppressor set up that’s also built to withstand rigorous use. This is our prescription for the shooter who cares about the aesthetics of their build as well as its ease-of-use.

Some of the exciting new benefits of the YHM sRx System are as follows:

  • TIMELESS. (No need to shim/time to barrel)
  • Small/low profile
  • No moving parts
  • Large taper in front of the threads allows for consistent mounting.
  • Lighter than many Q.D. mounting offerings on the market
  • Can be permanently attached to firearm barrel needed

The YHM sRx System is just what the doctor ordered!
